The app, which is available on both iOS and Android, targets family members who want to cut through the noise of all the other social services and digital communication options available. The Life360 app uses location-based technology to show a map of all family members as well as a chat stream. While the entry-level app is free, Life360 also offers a premium service with more features for $5 per month.

The new round was led by DCM, with participation from existing investors. The startup says it plans to use the new capital to grow the service, expand into international markets, and integrate with home and car security systems.

Founded in 2008, the San Francisco, Calif.-based startup says it has about 40 million users and has raised a total of $20 million in funding to date.
